ALFRED P. BRILL, 01 PITTSBURGH, PENNSYLVANIA, ASSTGNOR TO RUUD MANUFAC- TURING COMPANY, OF PITTSBURGH, PENNSYLVANIA, A CORPORATION F NEW JERSEY WATER HEATER Application filed August 10, 1927. Serial No. 211,880.

This invention relates to water heaters and more particularly to the novel construction thereof.

ater heaters that have heretofore been 5 constructed are undesirable because of the amount of space required around the heater for removing the mechanical rigging due to the. location of such rigging. All of the heaters known to me have the mechanical rigging so disposed in the heater as to require working space on two or more sides for assembling or disassembling the rigging to or from the heater; that is, the thermostatic device is adapted to be removed from one side,

the burner from a second side and the drain cock and possibly other parts of the rigging from still another side. It can readily be seen that considerable space is required to install a heater of such construction and permit the removal of the Various mechanical rigging for inspection or repair.

An object ofthis invention is to provide a Water heater of such construction that shall permit all of the mechanical rigging to be removed from one side of the heater.

Another object of this invention is to provide a water heater of such construction that shall permit all ,of the mechanical rigging to be removed from the heater in a single sembled or disassembled to or from the.

heater. I Another object of this invention is to pro vide a water heaterhaving the above characteristics that shall be simple in structure,

practical in operation and inexpensive to manufacture.

These and other objects that may be made apparent throughout the further description of this invention are attained by means of the the Water heater hereinafter described and illustrated in the accompanying drawings V wherein, L

heater space or burner chamber 15 and-the.

necessary mechanical rigging represented in itsentirety by 16. The mechanical rigging comprises in general, a thermostatically con- 2 trolled gas valve mechanisms 17, burner 18,

automatic gas cut-ofi 19, mi'xiri'g tube 20, needle valve adjustment 21, main gas line 22, pilot line 23, pilot light 24, controlled by the cut-off 19, and drain cook 26. It can be seen from -the drawings that all of these elements are mounted in front of the heater and utilize less space than the diameter of the heater. The valve mechanism 17 is controlled by a thermostat 27 that extends through a' housing 27 and into the tank 14 as shown at 27. The

housing 27 is rigidly secured to the tank14 as shown at 27a.

Thetank is provided with an opening 28 inits'lower front portion for receiving the burner, mixing tube etc. The opening is provided with doors 29 having spring means 30 for biasing'the doors 29 to closed position and also with a latch (not shown) for looking the doors in open position.

v The rigging mechanism is provided with a" guide step 31 at the lower front portion of the mixing tube for engaging With a seat 32 on the lower front portion of the heater for maintaining the mechanism in proper position. A further guiding or positioning means is provided for limiting the movement of the burner into the burner chamber. which means comprises a tongue 33 fixed to the bottom portlon of the heater and a groove 34 formed in a lug or similar member provided on the bottom portion ofthe mixing or burner tube for engaging thetongue 33.. This assembly is shown in Fig. 1 and it can readily be seen that the manner of inserting or removing the burner, mixing tube, automatic gas cut-off is very simple, because the thermostatically regulated gas control mechanism and the burner are mounted on and supported by the thermostat housing 27 by means of the union 36 and the bolts 36.

When it is desired to remove the burner, mixing tube, pilot light, safety valve, automatic gas cut-off etc.,, it is only necessary to loosen either ofthe brass to brass unions of the main gas line and either of the brass to brass unions 35 of the pilot-line to with draw the entire mechanism located in the bot-. tom portion 15 of the heater. Should it be desirable to remove the entire mechanical rigging including the thermostatic device, burner, etc., then it is only necesasry to loosen the bolts 36 and the entire rigging mechanism can be withdrawn from .the heater in a single unit.

The present day construction of small houses and apartments require conservation of space and the value-of a heater constructed in accordance with this invention is obvious to those familiar with this art. It is often desired to install a heater in a limited space having three surrounding walls and in other spaces which would not permit the removal of the mechanical rigging from heaters'that have heretofore been provided. A principal advantage of this invention is the providing of a water heater so constructed asto permit the removal of its mechanical rigging in a single unit and from one side of the heater thereby rendering installation of such heater practical even with three surrounding walls. The heater above described provides these advantages and may be installed in a space having a front clearance equal to the diameter of the heater and permit the removal of all of its mechanical rigging from this space in a single unit or such portion thereof? as may be desired. i I

Other advantages lie in'the neat and compact arrangement of the mechanical rigging, the expedient mannerin which it can beinstalled in the heater or withdrawn for inspection and repair. c

While I have illustrated and described but one embodiment of this invention it will be apparent to those skilled inthe art that cerbelow the tank, of operating mechanism including a thermostatic member extending into said tank from one side of said heater, a burner tube extending into said chamber from the same side of said heater, positioning means for said burner tube located in said chamber, a grooved member associated with said burner tube so as to cooperate with said positioning means. upon movement of said burner tube into said chamber, means for detachably connecting said burner tube and said operating mechanism together so as to form a unitary mechanism movable as a unit into and out of operative position, and means for supporting the unitary mechanism on the heater.
